Motor-drive solution for light electric vehicles based on a switched reluctance machine

Abstract

Worldwide nowadays there is a serious tendency of passing from internal combustion engines to electrical or hybrid propulsion systems. On this trend, the paper details the itinerary from concept to numerical validation of an electrical propulsion unit, dedicated for a light electric vehicle which is equipped with a switched reluctance machine (SRM). Starting from the design concept, analysis via complex simulations, appropriate power electronics and wise control strategies for torque smoothening, all the steps are presented, some of them in detail. One of the goals of the study is to maximize the efficiency and comfort ratings, by keeping in mind the most reduced investment, offering a complete design-numerical solution that can be extrapolated to higher power ratings.
